TO ALL WHOM IT M-AY CONCERN: v

VBe it kno-wn that we, Josnrn Knnnsand Aueus'r Jonas, of Massilion,jn the county of Stark, and State oi Ohio, have inventeda new and usefullinprovenient in Corn-Planters; and we do hereby declare that the following is afull, clear, and exact description thcreowhich willenable others skilledin the art-"to make and use the same, reference being had to the'aceompanying drawings, formingpar-t of this speciiicntion, in which- Figure lis a front view of our" improved machine, partofthegrnin-box beingr broken away to show the dropping'device. i n v` v I Figure 2 is a vertical section' ofthe same taken 'through theline a: a', fig. 1. Figure 3 is a detail sectional view of the dropping-,wheel taken through the line y y, fig. 2. Similar letters of reference indicate corresponding parts. I Our invention has for its object to furnish-.an improved machine by means of which'tho ground may be furro'wed, the corn dropped and covered, and the hill-marked, by the saure operation, and which shall at the A same time be' simple in construction and easily operated;` and` it consists in the` construction., combination, and arrangement of -the various parts of 'the'xnachima .as-hereinaftermore fully described. Y y are the w-heels,and B is the axle of. the` machine, to which isv attached'the frainework C.A D is the seedbox, which isfsu'pported upon -and vattached to lthe npp'e'r'ends of lfonibars, E, the' lower ends ntf whieh are. "inticlied-to the axle andiame '.lo one of AAthe WlteelsA is attached a large cog-wheel, F, into the teeth ofwhiohmeshthe teeth of the small cog-wheelG which is attached to the end of the shaft Hf The shaftH rev'olves'in bearings or supports I attached to the axleB, and has'a bevel gear-wheel, J, revolving loosely upon it. In the outer end of the hub ofvtliewheel J is formedv a groevein which rides 'the forked end of the connecting-rod Kthe other lend of which isvpivoted to the lever L, the .lower endfof which is pivoted to an arm i or support, M, attached'to thel frame-C, as 'shown in figs. 1 and 2, and the.pper end of which entends up into Suche position that it may be reachedand operated' bythe driver. The lever L is held in position,when adjusted,.by notches formed in the slotted plateN'attached tol the endfof theseed-box D. Upon the -inner end of the hub. of thefbevel gear-'wheel J is formed a clutch which corresponds with the* clutch adjustably attached to the lshaft so that-.by moving the said gear-wheel .J forward the clutch O'. may cause'it to revolve with the revolution of the shaft' H. I ismaV vvertical shaft, the lower endl of" which revolves in a socket in the support R attached tothe axle B, and thel upper cnd'of which passes up into the seed-.box D. S jis a` bevel gear-wheel attached to the 4vertical shaft-P in such aposition that vits teeth may mesh into the teeth ofthebevel gear-,WheelA 'J-vi'hen said gear-wheel is moved forward to'the clutch O. To the upper end of the vertical shaft I is attached I a wheel,e T; which revolves within the seedbox D,vcloseft4o its bottom, and whichl has an opeuingor chamber, It,4 forined in the side of its lower part,'of such. asiae as to hold the desired number of kernelsfor each bill. U fis a. plate. attached to 4the fee`dbox D, withits edge near the face of the wheelT, to prevent any grain entering the discharging-spout e'xceptthat carriedlin the chamberv't of' the wheel T, .V is a horizontal partitionplaced Ain the seed-box D to prevent the corp; in said seed-boit frompassing down upon .all sidesof' the wheel T' and cloggihg its'motion; onepart'oi said partition being cut awayto"allowv thecorn to descend at one sideof the wheel T, so as to be carried by the chamber t to the discharging-'spout W,the upper endof 'which is conA .nectedI-with the dischargingoritice=in the bottom of the seed-box D, and thelowerend of which is connected withthe hollow standard Xof the shovel-plough Y which opens" the {ni-row. foi-",'there'ceptionof the seed, vso as to drop the seed; in said. furrow close to the rear side of saidplough. The staiidard X is securely'at-tached to the frame C. A are the covering-ploughs, the standard-s B of which areadjustably secured to ltheY axle B, in the rear'and at each side of the standardl X', by the catch-plate C pivoted to the axle B, and the edge ot'- which 'enters one or the otherof the notches or grooves formed in the said standardsB, so as to hold the plcughsi- -at any-desired elevation.
